A comparison of RAPD versus microsatellite DNA markers in population studies of the Massasauga rattlesnake

Article Abstract:

A new study compares the use of randomly amplified polymorphic DNA markers and microsatellites in the measurement of population differentiation in the endangered massasauga rattlesnake.

Insights into population ecology and sexual selection in snakes through the application of DNA-based genetic markers

Article Abstract:

Research into the genetic parentage of the northern water snake has revealed a variety of previously unavailable data, including high levels of multiple paternity. The benefits of hypervariable genetic markers to the study of snakes is emphasised.

Characterization of DNA microsatellite loci from a threatened snake: The Eastern Massasauga Rattlesnake (Sistrurus c. catenatus) and their use in population studies

Article Abstract:

Six microsatellite DNA loci from Sistrurus c. catenatus, the eastern massasauga threatened rattlesnake species, were isolated and genetically characterized. The loci was used to provide several population-level analyses. The loci were found to be highly variable, with detected alleles ranging between four and 12, and to segregate in a Mendelian fashion. They may not evolve by a stepwise mutation model and amplify similar size sections in other snake species.
